Mikeís workbench
« on: February 10, 2020, 07:00:11 PM »
Following joining this forum last month, hereís the first news of whatís on the workbench at the moment.

I said I first got into N gauge about 1971, with a Mk1 Jubilee, some Cavndish Stanier coaches and memories of seeing David Jenkinson with Garsdale Road at Leeds Corn Exchange, October LMRS exhibition 1970.  I was hooked on MR/LMS & S&C in the Yorkshire hills. 

So spin forward half a century, and Iíve rescued some Peco Jubilee bits to become part of the motive power for a planned S&C cameo.

These are both Mk1 versions, like my very first.  Thereís nearly two full models, BUT one and a half sets of valve gear and motion, only one dead motor, and one very dropped and battered loco body.

Onto the workbench, one loco body will rescue, new etched steps to replace those broken off, new brass buffers, again to replace impact damage.  One tender body had failed split through from impact, these are very thin alongside the vertical can motor.

The motor was installed the wrong way round, not connected, and open circuit.  Removed the motor, one brush without its spring was jammed in the holder.  Cleared out, commutator fully cleaned, polished and new Fleischmann brush sets fitted, it set off at a gentle purr on 2.5v.  Solid engineering there, 40+ years old, and itís only a three pole motor! Someone had started work on repairs with these bits, as one power chassis base is brand new as is the power transfer on the drawbar.

The other loco body is not reuseable, but it has yielded a spare single chimney to go on another rescue with an inappropriate double, a smoke box door and section of smokebox, and an entire cab moulding, which are no longer available as spares.  More of what they will end up as on another visit.

Next posting will show how the erecting shop is rescuing the loco body.

The pile of Jubilee parts shown in my last post has been sorted through. Thereís one good running tender drive chassis, one with no motor providing spares for three others, and two locomotive chassis and one serviceable loco body.
 


The photo is of the good loco body, and one full rebuild of a Mk1 gear linked loco chassis.  The original crankpin screws were not in the spares lot, so Iíll have to make those when this is all finalised.

This one will get a new tender drive, a Union Mills 6í6Ē axle centres unit bought new, which is getting a BHE cast kit 3500 gal Fowler tender body.  The loco has been built up with the conductive wheels swapped to the RHS, so the UM chassis can retain its standard LHS live to chassis pickup.  Iím keeping the conducting drawbar concept to connect the loco and tender.

Iíll describe and illustrate that work when I get to it later this year.

I have another Mk2 Peco Jubilee further on in restoration and repaint.  Itís in the paint shop now, and the tender drive is being reworked to take a Zimo DCC decoder. I have proved out the ability of the decoder to give fine, crawl speed control of the old 3 pole motor, so modifications to the chassis block are shown below. The mod involves sawing out a shelf at the rear of the tender, but the loss of metal has only dropped the adhesive weight by 4 grams.



Iíve cut slots for the cables to the pickups and the motor brushes.  This will be reassembled finished and ready to use as the paint shop work completes, and the tender drive wheels have had the flanges turned down to just over 0.5mm to match current modern n gauge standards and allow running through N finescale turnouts and crossings.

Next stage is get the old Unimat out for some engineering.

Iíll post again next week

Mike

An auction site buy needed a lot of TLC. Mechanically that is a work in progress,but here are some repaint progress photos. Repaint is to lined crimson with red shaded insignia, as Orion, using thePC Models transfers commissioned by Peco for the NL22, andFox lining transfers. This is my first n gauge repaint, and I learned a lot from the mistakes. The photos show where I need to do some touching in.

I also haveíFuryí going through rebuild and painting which will have the Sans Serif yellow insignia. Thereís so many options with a Jubilee.

Before - as newly arrived from the auction buy



Then hereís the body parts ex paint shop, this is many hours of spray painting, hand and transfer lining and lettering. A good couple of months of spare time.



Temporarily erected on a standard Jube chassis, itís final one is having wheels reprofiled to RP25 dimensions, the cylinders are not itís finished set.




Tender lining on the back of the tender, so many rivets to fit transfers over, it is cruel magnification. Very fiddly.




Next post will hopefully see  Orion complete on reprofiled, blackened wheels and motion, with a DCC decoder to control the original motor.

If all else fails get a Union Mills tender drive. However the pick ups on the loco are the same side as those on the UM tender so either the tender wheels and axles or the loco ones need turning over.

Re loco body and motorI think I might have one of each having used the chassis for an SR N15, I'll do a search of by bits boxes.
Cheers MIKE
